# The `sort` command
|
|
|
|
the `sort` command is used to sort a file, arranging the records in a particular order. By default, the sort command sorts a file assuming the contents are ASCII. Using options in the sort command can also be used to sort numerically.
|
|
|
|
### Examples:
|
|
|
|
Suppose you create a data file with name file.txt:
|
|
```
|
|
Command :
|
|
$ cat > file.txt
|
|
abhishek
|
|
chitransh
|
|
satish
|
|
rajan
|
|
naveen
|
|
divyam
|
|
harsh
|
|
```
|
|
|
|
Sorting a file: Now use the sort command
|
|
|
|
Syntax :
|
|
|
|
```
|
|
sort filename.txt
|
|
```
|
|
|
|
```
|
|
Command:
|
|
$ sort file.txt
|
|
|
|
Output :
|
|
abhishek
|
|
chitransh
|
|
divyam
|
|
harsh
|
|
naveen
|
|
rajan
|
|
satish
|
|
```
|
|
|
|
Note: This command does not actually change the input file, i.e. file.txt.
|
|
|
|
|
|
### The sort function on a file with mixed case content
|
|
|
|
i.e. uppercase and lower case: When we have a mix file with both uppercase and lowercase letters then first the upper case letters would be sorted following with the lower case letters.
|
|
|
|
|
|
Example:
|
|
|
|
Create a file mix.txt
|
|
|
|
|
|
```
|
|
Command :
|
|
$ cat > mix.txt
|
|
abc
|
|
apple
|
|
BALL
|
|
Abc
|
|
bat
|
|
```
|
|
Now use the sort command
|
|
|
|
```
|
|
Command :
|
|
$ sort mix.txt
|
|
Output :
|
|
Abc
|
|
BALL
|
|
abc
|
|
apple
|
|
bat
|
|
```
